Five different types of β-diketiminate ligands, bearing electron-donating to strongly electron-withdrawing substituents, were synthesized and used in the synthesis of Cp* ruthenium complexes (Cp* = η5-C5Me5). One series consists of complexes with a covalen ...
Oxidation of the antimicrobial agent triclosan by aqueous ozone (O-3) was investigated to determine associated reaction kinetics, reaction site(s), and consequent changes in antibacterial activity of triclosan. Specific second-order rate constants, k(O3), ...
N-[2-(hydroxymethyl)phenyl]pyrrole was found to be amenable to selective a-metalation. Trapping with a variety of electrophilic reagents afforded the expected products with moderate to high yields. Derivs. formed by treatment of the organometallic intermed ...
The reactivity of stable tertiary enamides in nucleophilic addition reaction with various in-situ generated imines was explored. Under very mild conditions, formyl-bearing tertiary enamides reacted with both aromatic and aliphatic amines to form imine inte ...
Numerous inorganic and organic micropollutants can undergo reactions with chlorine. However, for certain compounds, the expected chlorine reactivity is low and only small modifications in the parent compound's structure are expected under typical water tre ...
This thesis is divided in seven main chapters including an introduction about the state of the art in the field, four main chapters describing the main part of the work, a short insight on the implications of the presented results for other research projec ...
The pi-facial selectivity of attack of electrophilic species (OsO4, m-ClC6H4CO3H, BH3) on the sterically unbiased dimethyl (1R,2R,3S,4S)-bicyclo[2.2.2]oct-5-ene-2,3-dicarboxylate is controlled syn to the exo electron-withdrawing ester substituents, and the ...
The enzymic oxidn. of isoniazid by the catalase-peroxidase of Mycobacterium tuberculosi was studied. The reaction products suggest two reaction pathways involving both electrophilic and radical species. Labeling expts. are consistent with a reaction mechan ...
Zinc iodide‐catalyzed cycloaddition of furan to 1‐cyanovinyl (1′S)‐camphanate or 1‐cyanovinyl (1′R)‐camphanate led to optically pure (1R,2S,4R)‐2‐exo‐cyano‐7‐oxabicyclo[2.2.1]‐hept‐5‐en‐2‐yl (1S')‐camphanate and (1S,2R,4S)‐2‐exo‐cyano‐7‐oxabicyclo[2.2.1]he ...
